Abstract
The utility model relates to a kind of novel plasma cutting rotating the arc generating means, described device comprises plasma cutting torch, drive the motor of cutting cutting torch rotation, for connecting the gear drive of motor and cutting cutting torch, described motor drives cutting cutting torch to be rotated by gear drive.Advantage of the present utility model is as follows, 1) whole apparatus structure is simple, and cost is low, easy to operate, reliability and stability are high; 2) the utility model utilizes the rotation of driven by motor plasma cutting-torch, realizes the rotation of plasma-arc, and the speed of electric arc rotation is easy to regulate; 3) this technical scheme is practical, easy and simple to handle, is convenient to large-scale promotion and uses.
Description
Technical field
The utility model relates to a kind of arc generating device, relates in particular to a kind of novel plasma cutting rotating the arc generating means, is applicable to the occasion that needs article on plasma arc cutting to be rotated.
Background technology
In plasma arc cutting field, a topmost defect is exactly that scarfing face is prone to oblique angle, and whole scarfing presents V-shape, and as shown in Figure 1, and cutting speed is faster, and oblique angle is larger.This is very unfavorable concerning obtaining the otch that perpendicularity is very high, has caused strengthening the workload of following process.In order to reduce the size at this oblique angle, Japanese little Song Industry Co., Ltd develops the plasma arc cutting of " cyclone " formula, and its principle as shown in Figure 2, tries every possible means electric arc to rotate, under the actual cutting speed on diagram right side reduces, by V
1become V
1-V
2thereby, obtain one-sided vertical scarfing.In order to obtain the effect of electric arc rotation when plasma cuts, be all the accessory that adds a kind of being called " ring of eddy " in the middle of cutting torch at present, as shown in Figure 3, adopted double-deck ring of eddy in figure, its effect is in order further to improve rotate effect.This mode forms a kind of rotary gas after making plasma gas enter ring of eddy in down carrying way, thereby realizes the generation of rotation plasma-arc.Although this method has solved the generation problem of rotation plasma-arc to a certain extent, has following shortcoming.The one, the rotary speed of electric arc is subject to the restriction of ring of eddy internal structure, and speed is slower; The 2nd, the rotary speed of electric arc cannot regulate.
Summary of the invention
The utility model is just for the technical problem existing in prior art, provide a kind of plasma simple in structure, easy to operate, that reliability and stability are high to cut rotating the arc generating means, can greatly improve the speed of electric arc rotation, and rotary speed can conveniently regulate.
To achieve these goals, the technical solution of the utility model is as follows, a kind of novel plasma cutting rotating the arc generating means, it is characterized in that, described device comprises plasma cutting torch, drive the motor of cutting cutting torch rotation, for connecting the gear drive of motor and cutting cutting torch, described motor drives cutting cutting torch to be rotated by gear drive.Realize the rotation of plasma arc cutting and rotary speed be easy to regulate, whole device reliability and stability are very high.Motor driven gear transmission realizes the generation of plasma cutting rotating the arc to cutting torch.During work, plasma gas enters bearing inner race through joint sleeve and enters in the middle of cutting torch again.
As a kind of improvement of the present utility model, described device also comprises that Internal and external cycle scribbles the bearing of high temperature resistant heavy current conductive grease, plasma tracheae, cable and joint sleeve, and described joint sleeve is for connection bearing and plasma tracheae and cable.In cutting torch rotary course, avoid like this tracheae and cable to rotate and produce winding with cutting torch, the conduction that also can realize cable and cutting torch is connected.Adopt bearing to connect cutting torch and sleeve pipe, the reason that recycling sleeve pipe connects tracheae and cable is to prevent in cutting torch rotary course, and tracheae and cable form wrapping phenomena along with cutting torch rotation.Wherein between bearing enclose, why will scribble high temperature resistant heavy current conductive grease, be because the conduction that need to utilize bearing to carry out between cable and cutting torch connects.
As a kind of improvement of the present utility model, described device also comprises the Wear-resistant, high-temperature resistant sealing ring of airtight plasma gas, and the quantity of described sealing ring is two.Realize the airtight of article on plasma working gas.Why adopting Wear-resistant, high-temperature resistant material to make, is in order to reduce the loss of sealing ring.
With respect to prior art, the beneficial effects of the utility model are as follows: 1) whole apparatus structure is simple, and cost is low, easy to operate, reliability and stability are high; 2) the utility model can be realized the High Rotation Speed of plasma arc cutting, also can facilitate adjusting to rotary speed; 3) this technical scheme is practical, is convenient to large-scale promotion and uses.

The specific embodiment
Referring to Fig. 4, a kind of novel plasma cutting rotating the arc generating means, described device comprises plasma cutting torch 2, drive the motor 1 of cutting cutting torch 2 rotations, for connecting the gear drive 5 of motor 1 and cutting cutting torch 2, described motor 1 drives cutting cutting torch to be rotated by gear drive.Realize the rotation of plasma arc cutting and rotary speed be easy to regulate, whole device reliability and stability are very high.Motor driven gear transmission realizes the generation of plasma cutting rotating the arc to cutting torch.During work, plasma gas enters bearing inner race through joint sleeve and enters in the middle of cutting torch again; Described device also comprises that Internal and external cycle scribbles the bearing 7 of high temperature resistant heavy current conductive grease, plasma tracheae 10, cable 11 and joint sleeve 6, and described joint sleeve 6 is for connection bearing 7 and plasma tracheae and cable.In cutting torch rotary course, avoid like this tracheae and cable to rotate and produce winding with cutting torch, the conduction that also can realize cable and cutting torch is connected.Adopt bearing to connect cutting torch and sleeve pipe, the reason that recycling sleeve pipe connects tracheae and cable is to prevent in cutting torch rotary course, and tracheae and cable form wrapping phenomena along with cutting torch rotation.Wherein between bearing enclose, why will scribble high temperature resistant heavy current conductive grease, be because the conduction that need to utilize bearing to carry out between cable and cutting torch connects.Described device also comprises the Wear-resistant, high-temperature resistant sealing ring 9 of airtight plasma gas, and the quantity of described sealing ring is two.Realize the airtight of article on plasma working gas.Why adopting Wear-resistant, high-temperature resistant material to make, is in order to reduce the loss of sealing ring.
